My Question or Issue

I used to be able to add new station, which will appear at "your library" - "station". But I forget about this function for a long time. Recently I want to add a new drive and it doesn't work anymore. When I create a new radio from artist song or album, I can only follow the radio, which will appear in my playlist but not in my station. I still can see my old station which I created maybe years ago but no longer can add new station ... What's happening?
